It seems as if Sherlock Holmes is more popular than ever; whether it's Robert Downey Jr.'s slow-mo charmer, Benedict Cumberbatch's gruff genius, or Johnny Lee Miller's American-based version of Sir Arthur Conan Doyle's detective, audiences cannot get enough.

Sherlock Holmes has been a fixture in PC gaming for a number of years now with an ongoing series of adventure games recreating his most famous cases, such as The Hound of the Baskervilles, or facing off against Jack the Ripper. The Testament of Sherlock Holmes, however, pushes Holmes and Watson to their limits in an all-new case.
